对设施专用型耐热秋黄瓜新品种中玉的丰产性、单性结实能力、耐热性和抗病性等性状进行了比较研究.研究结果表明,中玉第一雌花着生于第4.8节,比唐山秋瓜(CK)低1.3节,其雌花数和坐瓜率分别较对照唐山秋瓜增加了34.2%和51.9%,单性结实能力达90%,约为对照的3倍;总产量高达6500 kg/667 m2,较对照增加35.5%;耐热性显著增强;对黄瓜霜霉病和白粉病表现为中抗,对枯萎病和细菌性角斑病表现为高抗,但与对照无显著性差异.

In the paper, we studied the characteristics of a new facilities heat-resistant autumn cucumber cultivar Zhongyu, including yielding ability, parthenocarpic ability, heat resistance and disease resistance. The results showed that its first female flower set on 4.8th node, which was lower than Tangshanqiugua (CK) by 1.3 nodes. The female flower number and fruit setting rate of Zhongyu, compared to those of Tangshanqiugua, had increased by 34.2%and 51.9%, respectively. The parthenocarpic ability of Zhongyu got to 90%, which was about three times of that of control. Its yield was about 6 500 kg/667 m2, which was 35.5% higher than that of control. Its heat resistance was also significantly enhanced. It was moderately resistant to downy mildew and powdery mildew, and highly resistant to Fusarium wilt and bacterial angular leaf spot, but the disease resistance between Zhongyu and Tangshanqiugua had no significant difference.
